Neuque n, facing a high stroke incidence, established the first Argentinean legislation for stroke management, including prevention, acute treatment, and rehabilitation. The law led to the creation of the Provincial Stroke Network and inclusion of alteplase in the Neuque n Therapeutic Formulary. Results demonstrate advancements in healthcare delivery, with significant implications for public health policy and stroke management in Argentina. The study highlights challenges, particularly during the COVID-19 pandemic, and suggests future directions for comprehensive stroke care.","PeriodicalId":93502,"journal":{"name":"SVOA neurology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterized by a wide range of onset, from antenatal and infantile periods to early childhood and later adulthood periods. The early childhood form is considered the prevailing form, characterized by a preceding phase of normal development until the second or 3rd year of life, followed by progressive neurologic deterioration, accentuated by certain stressors, such as infections or minor trauma. Diagnosis is achieved based on the clinical pretext combined with distinctive MRI brain features, confirmed by DNA analysis detection of elf2B mutation. Our case is a healthy 18-month-old male who after a preceding upper respiratory tract infection, developed an ataxic gait, encephalopathy, and recurrent generalized seizures. Physical assessment revealed signs of generalized spasticity and hyperreflexia. Neuroimaging revealed diffuse symmetric supratentorial and infratentorial diffuse white matter hypomyelination. Interestingly, there was notable enhancement of the 3rd and 5th cranial nerves. Differential diagnosis included acute demyelinating leukoencephalopathies; and neuromatobolic disorders with acute presentations (including leukodystrophies, hypomyelinating disorders, and mitochondrial encephalopathies). In the early course of his management, he received immunomodulatory therapy in the form of pulse steroids, intravenous immunoglobulins, and oral tapering course of steroids. He had limited response to these interventions. Whole exome sequencing yielded a homozygous mutation in EIF2B3, confirming the diagnosis of VWMD/CACH. The presence of enhancing cranial neuropathies represent an atypical phenotype reported in other case reports and should alert the physician to avoid unnecessary intervention with immunosuppressive therapies.","PeriodicalId":93502,"journal":{"name":"SVOA neurology","volume":" 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141831466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on evaluating different pre-, intra- and postoperative techniques and analyzes their advantages and limitations to ultimately improve the management of this type of brain lesion. Through a critical analysis of various scientific sources, this research aimed to synthesize existing knowledge on the topic. Magnetic resonance imaging plays a crucial role in diagnosing and managing brain tumors. Functional MRI identifies functional brain areas, but tumor-induced blood flow changes can affect its reliability. Connectome analysis provides information on functional localization and brain networks, which became possible using diffusion tensor imaging, that visualizes white matter pathways, aiding in tumor boundary delineation and surgical planning. Studies suggest this method can predict tumor histology and prognosis. Intraoperative MRI improves the extent of tumor resection and potentially patient survival. But due to its limitations it has alternative intraoperative techniques, like intraoperative ultrasound, fluorescence-guided surgery, direct electrical stimulation, deep brain stimulation, but evidence for most of these methods is limited for most brain tumors. Only ultrasound showed real-time tumor visualization and residual disease analysis offering high accuracy and is relatively inexpensive compared to ioMRI. This study can be useful to neurosurgeons, neuro-oncologists, neurologists, neuro-radiologists, and will demonstrate prospects for further research.","PeriodicalId":93502,"journal":{"name":"SVOA neurology","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141829515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, due to the young age of these patients, they are difficult to manage and have a higher risk of complications in the treatment. In addition to this, patients are born with alterations in the development of the central nervous system due to chronic intracranial hypertension caused by said tumor and have little functional development.

The aim of this study was to determine the frequency of different types of artifacts in electroencephalography of the brain of hospitalized and outpatient patients referred to the clinics of Al-Zahra Hospital and Khorshid Hospital in Isfahan. Methods: In this cross-sectional study that was performed in Al-Zahra and Noor hospitals in Isfahan in 1399, 256 patients were studied by electroencephalography and examined for their electroencephalography, the presence of physiological and non-physiological artifacts and the source of artifacts in them. Results: Out of 256 patients studied, in 237 cases (92.6%) the artifacts were physiological and 19 (7.4%) were non-physiological. The type of physiological artifacts included 217 cases (91.6%) ocular, 1 case (0.4%) cardiac, 5 cases (2.1%) sweating and 14 cases (5.9%) motor. Among non-physiological artifacts, 11 (57.9%) were electrode and 8 (42.1%) were external artifacts. There was no significant difference in the type of artifacts performed according to the age and sex of the patients. Conclusion: The findings of the present study show that the presence of artifacts in patient’s electroencephalogram is very common, and among them, physiological ocular artifacts and non-physiological electrode artifacts are the most common errors in patients’ electroencephalogram and therefore it is necessary to Investigate the possibility of different types of artifacts and take the necessary strategies to reduce them.","PeriodicalId":93502,"journal":{"name":"SVOA neurology","volume":"82 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140742439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common clinical presentation is anterior spinal artery syndrome, a sudden-onset pathology with neurological involvement and devastating and disabling consequences for the affected patient. Its manifestations vary depending on the level of occlusion in the affected area.
